lVith the above and nume1'ous "otl1er ob jects in view as will appearas the description proceeds, the invention re'sides in certain novel features ofconstruction as will be here tndinalchain and numeral 6 cross chains. ThIS chain 5 has lncorporated therein my improved device,-Which maybe duplicated as This improved device comprises a pairof cup-shapedmembers 7 each of which has a cylindrical body A, and a single end disc B which is provided with a pair of adjoining OE-center circular openings 8. A pair'jot bolts 9 are slidable through the openings 8 and'have at their ends head 10 and eyesll.

The head 10 of one bolt is oppositely dis disc plates, 7 notches to receive the bolts, so that said bolts 1929 Serial No. 355,490.
